摘要：

(Figure Presented) Benzyl and tropyl in charge: Electronic spectra of mass-selected benzylium (Bz+) and tropylium (Tr+) cations embedded in solid neon are reported for the first time. They reveal a weak (1)1B1←X1A1 visible (see picture) and a much stronger (1)1A1←X 1A1 ultraviolet transition for Bz+ (C 2v symmetry). The lowest dipole-allowed 1A″2← X1A′1 absorption in the ultraviolet region for Tr+ (D7h) is also observed. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA.
